Carry out professional welding work and understand some conventional knowledge, so that you can have a bottom in your heart even if there are some problems. The welding machine operated has certain requirements for air pressure. It's not good if it's too high or too low. It can't run if it's too low. If it's too high, it will crush the plastic parts. What aspects of air pressure should we pay attention to?

Different plastic materials determine the pressure required during welding. Choosing an appropriate pressure value has a very important impact on the welding results. Too high pressure will lead to unreasonable use of vibration energy, resulting in excessive friction, weakening of friction movement between weldments, and even affecting the amplitude. As a result, the connection area between weldments does not increase, but decreases, and the strength of solder joints will also decrease.

If the welding pressure is too low, the ultrasonic vibration can not be well transmitted to the weldment, resulting in insufficient friction between the weldment and the welding surface. A large part of the energy will be consumed on the sliding surface, resulting in poor welding.

When ultrasonic welding, the size of air pressure can be selected according to the melting point (the higher the melting point, the greater the pressure value) and the size of plastic parts (the larger the size, the greater the pressure value). The pressure value of common ultrasonic welding machine is set as 0.4-0.6mpa.

Air pressure is a factor to be considered for the ultrasonic welding machine, and normal maintenance is also essential, which can reduce the failure rate and prolong the service life of the welding machine. Some general information attributes of the welding machine should be understood, so that it will be clearer in the process of use.
